conv.to can do that:

import std.conv;

enum LogLevel { ALL, INFO, WARNING }

void main()
{
    enum l = to!LogLevel("INFO");
    assert(l == LogLevel.INFO);
}

There has been discussions about that not too long ago.

Thanks. I have now implemented a logging library that actually 
looks to imitate log4j. If I log to any level then it checks if 
the current logLevel is equal to or lesser than the incoming 
loglevel. It might be using the wrong scale, e.g. ALL is 6 and 
OFF is 0, but it works. And its not really log4j so who cares ;)
